• If activated by set_wobbel_control and
set_wobbel_mode
(
Mode
= 2 ), the following
applies:
– The RTC6 varies the current laser power P within the wobbel shape section according
to
with 1 i wobbel vector number and 1 n
Period
i
. n represents the current
number of each Microstep. Nominal laser power P
nom
is set by the list command
set_wobbel_control.
– If activated by set_multi_mcbsp_in or set_multi_mcbsp_in_list, the nominal laser
power P
nom
is multiplicatively varied by the laser power parameter
P
across multiple
McBSP transfers: P
nom McBSP
= P
nom
×
P
/ 16,384.
– Beware here that for each both corrections above a maximum laser power of only
P
nom
× 4.0 is allowed, whereby the maximum range of the laser control parameter
likewise must not be exceeded (see set_wobbel_control).
– For laser power variation with
Ctrl
= 5 (half period),
dPower
needs to have the
opposite sign. Unlike with “Automatic Laser Control“, the multiplication factor
cannot be inverted.
– By using an “empty” wobbel shape
set_wobbel_vector(0.0, 0.0, 1, 0.0),
you can
also multiplicatively vary the nominal laser power P
nom
without needing to explicitly
wobbel (for another alternative, see set_multi_mcbsp_in).
– When you switch off the wobbel shape (not by deactivation by set_wobbel_mode),
the nominal laser power P
nom
is emitted at the port assigned by
Ctrl
if
set_wobbel_control has been last called with
Value
= 0xFFFFFFFF. Otherwise, the
laser power P
nom
multiplied by the external factor from set_multi_mcbsp_in is
emitted.
